' in the cit;r of New York, borough of Men hutten, in the county and State of New York, JULES DAwANs, n subject of the King of Belgium, residing at L ndhurst, Bergen county, in .the Stute of hew Jersey, and GUsTAv EKLUND, n citizen of the United States, residing at the city of Nmvrork, borough of the Bronx, in the' county un State of New York, have invented cert-nin `-'new and useful Improvements in T.ong-Time Burners, of which the followin is u full, clear, and exact specification.

" Our invention relates to improvements in lamp burners, of the type known as long time burners, and the same has for its object to provide a simple, ellicient and reliable burner :for signal and other lamps, which burner will "produce a fiat flume yielding a geleen steady white light. Further said invention hus 'for its object' to provide n long time burner employing n round wick ind producing n tint fiume Without the use of e chimney.

Further said invention has for its object to rovide mburner more particularly adopted or use in signal and semaphore humps havi lenses nrranged in two or .more of their sides, and which burner will permit of the easy :rdj ustment of the` Home in order that its lister broad side may he arranged parallel with the inner surface of one or more of the surfaces of' seid lenses.

Further said inwintion has for its object to provide nhurner in which the linmespreading or llnttening menus-hwy he readily adjusted to change the. angle of said flame, without necessitating the detuching of the burner from its oil font, or changing the position of seid oll font within the lontern.

Further said invention has for its object to provide n. burner in which the workixlg parts may be. readily tnlen npnrt to permit of the elennin f ol? the burner and the dressing of the wie To the nttninment ol the niort-said objects :md ends, our invention, consists in the novel details of ormstl'llotion, :ind in the combinaition, connection :und :u'rnrigelinnt oli pouls hereinafter more lull)I described :unl then poinlml mil. in the. clAimS'.

In said drawings, 10 designates the base portion of a burner having a reduced-end 11 which is screw-threaded for application to the oil font. 12 denotes an annuler rim arranged upon the side of said base adj ncent toitstop. y

13 denotes the wick tube which extends centrally through said base 10, and end 11, und has its u per portion projecting above the upper si e of said base 10, and its end provided with a cuE 11i having nir ports 15, 15 arranged Vin the ottom thereof. f

16 denotes the Wick reis'ingr'ehaft which extends into said base 10, and 1s rovided at its inner end with a ratchet whec extending through an openin in the wick tube and enguing the wick t ikein. i

The u )per portion or top of said ccp 17 is provi( ed aiimg'its odge with {onr equidistnntly arranged recesses 18, 18" which open into circumferentinl. slots 19, 19 arranged in thevertiexll side portion 'of said cup. The

The tapering Wall of said cone 22 is provided near its lower edge but above the studs Q3, Q3, with a horizontal row of air inlet openings 24, and the upper end of said cone 22 is provided with a constricted throat 25, inwhich rigidly secured a Ilame spreader comprising a slightly tapering neck section 26, which extends from the u per side of the cup 14, tothe upper edge o the throat 25, and a. pair of inclined plates or wings 27, 27, having their lower ends in contact with each other. Each of said plates or wings 27,' Q7 has its inner cdge'provided with a semi-circular recess, which jointly ner contacting ends of said plates or wings, which opening corresponds substantially in diameter with the interior of the cup 14, The upper edges of said. plates or Wings are cach provided at their opposite ends with semi-circular projections 28, 28.

1 The upper ends of said plates or wings 21', 9.7, which projectabove the top edge of the throat 25, are firmly secured in position within said conc 22 bysupports 29, 29,

'i which havc'tlucir upper .ends secured to the outer sides of the projecting portions-of said plates or Wings 27, 27,', and their lower ends extending through openings provided in the top of said cone, and then suitably secured against the inner side thereof. The operationof the burner is as follows:

In order vto can se the lamp arranged within a signal lantern 'containing a plurality of lenses to burn with its fiat llame parallel -with the` inner surface of the particular lens, or lenses, (if saine are arranged oppositely to each other,). it merely becomes necessary to adjust the cone 22, relatively to the base 10 .in such manner that' the spreznlcr plates 27, will have their inrined edges parallel with such lens or lenses. AThe cone will be heldl firmly in po sition upcn the base Il) by the frictional lengagement of thel studs 23, 253/, with the indenl'atious 21, 21, arranged in the top of the rap 'li' directly above the inner ends of the Sha.; ll), lila. the proper amount of oxygen to the ame being received partly through the air inlets 2l in the come the air vents l5, l in the base ofthe cui ll, and over the lower contact-ing edges uff the inclined plates or ning-- is desired to change the horll/Vlien it; Zentral longitudinal Axis of the 'tame 1n order that the SMB shall he parallel With the lens or lenses arranged in other sides o@ the, lantern, it merely becomes neer-ssarjf t@ removehe cone 22. by releasing the studs 23. 23 theme? o? their engagement. with the raam 18. i8, and Slots i9, 18, and give l'ille air necessary to s'u )ply said cone a quarter turn in order to allow said studs to engage with theireccsses 18, 18, and slots 19, 19, thereby causing the .spreader plates 27, 27 to assume a position 'ing its burner fixed a't a different angle relatively to the lamp in-order to bring the flat` side of the ame parallel with the inner side of the lens, located in a given side of the ,lantern form a circular opening 28 between the 1n- 'Having thus described our invention, what we claim and desire to secure by Letters Patent is:- A
